n. pl. a·nas·to·mo·ses (-sz)

1. The direct or indirect connection of separate parts of a branching system to form a network, especially among blood vessels.

2. The surgical connection of separate or severed tubular hollow organs to form a continuous channel as between two parts of the intestine.

3. An opening created by surgery, trauma, or disease between two or more normally separate spaces or organs.

anastomosis

[ənas′tōmō′sis] pl. anastomoses

Etymology: Gk, anastomoien, to provide a mouth

1 a connection between two vessels.

2 a surgical joining of two ducts, blood vessels, or bowel segments to allow flow from one to the other. A vascular anastomosis may be performed to bypass an aneurysm or a vascular or arterial occlusion. With the patient under anesthesia, a section of the greater saphenous vein or a synthetic prosthesis is grafted to the prepared vessels. Postoperative nursing care includes preventing tissue injury and wound infection. Lack of blood flow may allow the graft to close. Pulses distal to the anastomosis are evaluated frequently. Capillary refilling time and the color and temperature of the skin are checked. Prophylactic antibiotic therapy may be started within hours. Urinary output is monitored. Kinds of anastomoses are end-to-end anastomosis, end-to-side anastomosis, side-to-side anastomosis. See also bypass. anastomose, v., anastomotic, adj.

anastomosis (pl. anastomoses) (nas´tmō´sis),

n the joining together of two blood vessels or other tubular structures to furnish a direct or indirect communication between the two structures.

anastomosis graft,

n the connection of two autogenous tubular structures as a part of reconstructive surgery.

anastomosis

1. communication between two tubular organs.

2. surgical, traumatic or pathological formation of a connection between two normally distinct structures.

arteriovenous anastomosis

anastomosis between an artery and a vein.

cobra-head anastomosis

a technique used in joining grafts to blood vessels. Ends of grafts are trimmed to form an enlarged lumen.

esophageal anastomosis

uniting the free ends after complete resection of a part of the esophagus.

heterocladic anastomosis

one between branches of different arteries.

intercarotid anastomosis

a naturally occurring communication between the internal and external carotid arteries in birds. It provides a collateral pathway for blood to the brain, the counterpart of the cerebral arterial circle of Willis in mammals.

intestinal anastomosis

establishment of a communication between two formerly distinct portions of the intestine.

skin arteriovenous anastomosis

frequent natural occurrence; capable of diverting large volumes of blood to splanchnic circulation during cardiovascular stress.

tracheal anastomosis

end-to-end anastomosis of the trachea after resection of a part.

ureterocolonic anastomosis

see ureterocolostomy.

anastomosis 

A natural communication between two blood vessels or other tubular structures. Example: the long posterior ciliary artery divides into two branches as it enters the posterior part of the ciliary muscle and at its anterior end these branches anastomose with each other and with the anterior ciliary arteries to form the major arterial circle of the iris. See major arterial circle of the iris.
